For packet header dissecting, skb->protocol is needed. Add protocol parsing operation to vlan ops, to guarantee skb->protocol is set, as EtherType 0x88F7 occasionally follows a vlan header. Changelog: v4: - Drop a redundant length check when fetching ptp header from skb. v2, v3: - Add more people to the CC list.
